How to solve the problem about loading resx resources dll on iOS (.NET MAUI)


Background:

I want to do the localizations feature on my .NET MAUI app. I follow this video (https://youtu.be/cf4sXULR7os) to do that.

In the iOS simulator, the localization feature and loading the resources.dll is running preferably. (like the following)

But once I deploy it to my physical iPhone device, the feature does not work and outputs the following message when I change the language.
